Click to expand...

plug Into computer, then hold the two buttons (sleep & home) and KEEP holding them even when the iPod turns off. When it turns back on and you see the apple logo, let go of the sleep button (at the top) but KEEP holding the home button. It should then ask u to connect to iTunes. Restore to 1.1.4 and try the jailbreak again with the latest version of ziphone or iliberty+ (less risk for you if you follow a guide)
